Co-extrusion Composite Decking Production Technique
Wood plastic / plastic wood is a kind of profile mainly made of wood as the basic material, thermoplastic polymer materials (plastics) and additives. After the thermoplastic polymer materials are mixed evenly, they can be coated on the surface of the profile by die equipment and extruded to form a new type of plastic wood profile, which has the characteristics of wood and plastic. The weather resistance and quality stability of Co-extrusion Decking are greatly improved compared with ordinary composite decking, and it is the mainstream product of outdoor decking at present. During the use of the current mold, the thermoplastic polymer material will have the problem of uneven flow after passing into the mold cavity, resulting in the rough surface of the thermoplastic polymer material on the wood, and the poor water-cooling effect will lead to the deformation of the formed surface. An enterprise has proposed a production line and production process of plastic wood Co-extrusion profiles, which solves the problem that the surface of plastic layer of plastic wood profiles is not smooth during production in the existing technology.
